MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 678,459, dated July 16, 1901. Application fled March l5, 1901. Serial No. 51,277. (No model.)

To @ZZ whom it may concern.-

Beit known that I, CONRAD DIETZ, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

My invention relates to an improved mechanical movement for producing revolution alternately in opposite directions in the driven shaft.

One object is to produce a simple and strong mechanism for the above purpose.

Another object is to provide a mechanism having few parts,` a strong leverage from the driving-shaft, and a capacity to make one and a half or more turns of the driven shaft in eac-h direction before the reversal occurs.

Another object is to provide a mechanism` in which no lost motion occurs during or at the reversal of movement.

The invention also consists in certain details of form, combination, and arrangement, all of which will be more fully set forth in the description of the accompanying drawings, in whichm Figure l is a side elevation of a movement containing my invention. Fig. 2 is a horizontal section throughthe same on line ,e e' of Fig. 1. Fig. 3 is a perspective view of the gears on the driven shaft. Fig. 4 is a perspective View of one of the intermediate segmental gears. Fig. 5 is a section on line U o of Fig. l, showing the gears in position to reverse the direction of the driven shaft.

A represents the frame or housing in which the operative parts are mounted. This frame is provided with ears A', by means of which it is adapted to be secured in position for use.

B represents the driving-shaft, Which is provided at one end with a driving-wheel C,which may be a hand-wheel or a belt-pulley, as desired. At the opposite end of the drivingshaft is a beveled gear D, which meshes with beveled gears E E', which are preferably formedV integral with the segmental gears F F', which`are loosely journaled on the shaft G, which spans the central opening in the housing and is preferably pinned or otherwise se'- cured to the housing.

H represents the driven shaft, which is journaled in the housing A on opposite sides of the central opening.

' I I' represent spurgears secured to the driven shaft and adapted to engage the respective segmental gears F F' as they come opposite the driven shaft. The gears I I are preferably formed in a single piece, as shown in Figs. l and 3, with a connecting-collar J, through which a pin is driven to secure the gears to the shaft. Any desired tool or implement may be secured to the end of the driven shaft. It is particularly adapted, how# ever, to be applied to washing-machines, in which case the lower end of the driven shaft projects down into the tub and is provided with an implement for stirring the clothes about in the tub first in one direction and then in the opposite direction.

The operation is as follows: The drivingshaft isturned by means of the wheel C,

which through the gear D drives the beveled gears E E' in opposite directions. The segmental gears F F' are set opposite each other, so as to alternately engage the gears I I', and thereby drive the shaft H in opposite directions. The respective segmental gears engage to drive the shaft H as soon as the preceding segmental gear has passed out of engagement with the gears I I' and without any lost motion at the point of reversal, as indicated in Fig. 5, which shows the gears in the act of reversing, the last tooth of the segmental gear F being in the act of leaving or disengaging from one of the teeth of gear I, while the first tooth of the segmental gear F', which is vertically beneath the last tooth of gear F, is in the act of engaging the corresponding tooth of gear I' to immediately reverse the direction of the shaft H, thereby preventing any lost motion or failure of the gears F F to properly mesh with the gears I I' and producing a smooth, reliable, and even reversal of the driven shaft while the driving-shaft is being continuously driven in one direction. The gears E E F F' are counterparts of each other and require but one pat- `v tern.

Having described my invention, what I claim is- ICO 1. In combination with a drivinggear; gears adapted to be driven therefrom in opposite directions; segmental gears carried by said driven gears; a driven shaft and gears carried thereby adapted to be alternately7 engaged by the respective segmental gears to drive the driven shaft alternately in opposite directions.

2. In combination with a housing having a central opening; a driving-shaft journaled therein, a driving-wheel mounted at anypoint thereon; a driving-gear also mounted thereon; a shaft spanning the central opening in the housing; two gears loosely mounted thereon; and adapted to be driven from the driving-gear in opposite directions; segmental gears carried by said driven gears; a driven shaft jonrnaled in the housing on opposite sides of the central opening; gears rigidly mounted on the driven shaft and adapted to CONRAD DIETZ.
